Re: reqMktData callbacks are missing data with gateway 10.30 and 10.31 sporadically, works fine with 10.19 and older gateways/TWS

However I did notice 2 things

I just ran your sample program again, after hours w/ realtime, data_lines=75, loops=5 and everything worked OK using IBGW 10.30.1s. IDK what to say... I may try it again tomorrow since you indicate there's more likelihood of a problem during RTH.

However, I'm also wondering if your network connection may have slightly degraded in the recent past? Is someone streaming HDTV while you test, lol? Are you sure you can't reproduce the problem w/ 10.19? I suppose it's possible that 10.30 has just enough extra network demand than 10.19 to make a difference but...

I mention this mostly because my server has an exceptionally good connection (and I'm located close to the USA NE data center). When I look at your email headers I notice you're in Sweden, so if you're using a local computer... you might have more variation in connection quality. Just a guess since the code itself looks OK and the test results look OK.
